Detective Inspector Bruce Coutts said: “The 48-year-old man has suffered serious injuries as a result of this incident and was subjected to a sustained attack with a weapon.

“We believe the three men involved were all wearing black clothing and balaclavas covering their faces and used two vehicles during the course of the incident.

“I’m especially eager to hear from anyone who may have seen either the Audi A5 in the area of Pitcairn Grove immediately prior to or after the incident, or who saw the suspects leave the Oxgangs area in the silver car after abandoning the Audi in Harperrig Way.

“I’d also urge anyone who can help us identify those involved to come forward as soon as possible.”

Anyone with information is asked to contact 101 and quote incident number 3117 of March 13, or call Crimestoppers anonymously on 0800 555 111.
